I'PNEU MATIC SIGNALIN G APPARATUS.

SPECIFICATION: forming part;- of. Letters Patent No. 436,434, dated September 16, 1890.

Application filed April 12, 1889. Serial Ila-307,010. (No model.)

."To all whom it mayconcern:

. Be it known that I, JOHN T. PENNYCOOK, a citizen of Great Britain, residing at New 7 York, in the county of New York and State invention, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the'accompanying drawings, and to the letters'and figures of reference marked thereon,which form a part of this specification.

. My invention has relation to pneumaticannunciators or pneumatic signaling apparatus for hotels, public buildings, dwelling-houses, elevators, steamboats, and the like; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my improved pneumatic annunciator with one push-button connected to one of the indicators and shown in section. Fig. 2 is a front elevation of a pneumatic. annunciator embodying my improvements with its plateglass front and plate removed. Fig. 3 is a vertical sectional view on the line y y in Fig. 2, and Fig. at is a vertical sectional view taken on the line a; a; in Fig. 2.

' .Referring to the drawings by letter, A designates the rear wall. of the casing of the device, having attached a-bell and indicating mechanism, the bell; being at the top of said or opposite end of each tube 0 O is conas rubber.

nected to a case D, situated at the desired point, as within a room in a hotel or steamer,

which case contains an air-chamber E, the back and front of which are concave internally and composed of flexible material, such rests and moves in anopening in the front of the case D.

The frontF of the air chamber is I connected centrally to a push button G, that partially flattened and air will be driven through said tube to the indicator.

H I H are bellows-attached to the inner surface or back A over the openings B by means of the rings H preferably of. metal, which are secured in place by suitable screws,-as shown in Fig. 2.

I I are transverse rock-shafts journaled at their ends in angle bearing-brackets K, secured to the back A and extending over the alignedbellows immediately below.

L L are double angle-irons having their upper vertical arms secured-by screws to the back A, their horizontal parts extending frontwardover a shaft I and a bellows below said shaft, and their outer vertical dependingarms provided with bearingopeningsfor shafts P, hereinafter described.

M M are angle bearing-brackets secured by screws N, Fig. 3,'to the horizontal parts of the bracketsL, and dependingthence parallel to the arms 0 of the corresponding double angle-brackets L.

P Pare short shafts providedwith journals at their ends, having bearings in the corresponding depending arms of the brackets L M and surrounded by coiled springs Q, Fig.

3. Each of said springs has one end secured to the lower part of the corresponding depending arm 0 and the other end to the base of an arm S, extending laterally outward from the shaft P, which said spring surrounds. The said shaft is provided with a second arm R,

that curves laterally downward and inward engage in threaded openings inthe outer. edges of the horizontal parts of the corresponding brackets L, which parts are properly thickened where said openings are made. The longer rear arm of each of said levers bears at its end upon the face of the corresponding bellows H, and its shorter front arm is provided with a hook T, that engages under the arm S of the corresponding shaft P. When the said bellows is inflated by means of the push-button, air-chamber, and tubes 0 C, it moves the longer arm of the lever U frontward and causes the hook T to release the arm S. The spring Q then immediately rotates the shaft P in its bearings and causes the pointer or indicator-finger 22 to pass from a horizontal to a vertical position. The said finger is secured on the front journal of the shaft P, extended through an opening 1, 2, 3, or 43* in the front plate A of the case and within the protecting glass plate A of said case.

X X are arms projecting radially from the rock-shafts l and engaging the laterally-projecting arms Y of the vertical push-bar Z.

S D S D are semi-disks resting against the faces of the corresponding bellows and attached by arms to the shafts I. (See Figs. 3 and 4.) It is evident that when the said bellows is inflated the corresponding semi-disk will be moved frontward, partially rotating the shaft I and causing the arms X to lift the push-rod by means of its arms Y. The said push-rod is maintain ed in its vertical position by passing through a suitable opening in an angle-bracket secured to the back A. Fig. 4.) The upper end of said push-rod is pivoted to the end of a lever 1, mounted on a shaft 3, having bearings in the plates 4 and 5, which are connected by pillars similarly to the plates in a clock-movement frame, the plate 5 being secured to the back A. Upon the shaft 3 is also mounted a segmental gear 2, which meshes with a pinion 7, (a lanternpinion being shown in the drawings,) mounted on a shaft 8, that has bearings in the plates 4 and 5 at suitable points.

9 is an escape-wheel, also mounted on the shaft 8 and engaging the pallets of the escape-lever 10, mounted on the shaft 11, having hearings in the plates and 5. Standing from the shaft 11 is the hammer-arm 12, havingthe hammer 13 at its end in position to strike the inner surface of the bell 14, which bell is secured to the back A by the stem 15 and a suitable screw at the outer end of said stem.

15 is a retracting coil-spring secured to the back A at its lower end and at its upper end to the end of the lever 1, so that it will draw said lever down again after the latter has been lifted by the push-rod actuated by the means described. The upward movement of the push-rod and lever and the downward motion thereof, caused by the spring 15, will both obviously cause the bell to ring by means of the connecting-gearing and the escapement.

S S designate a spring-wire stop or detent to prevent the hammer from striking the bell too hard and to equalize the motion of the hammer.

(See

a a designate angular guide-brackets secured to the back A and provided with guideopenings 6 bfor the reception of the vertical setting-rod c. The said setting-rod is provided at proper points with the opposite laterally-projecting arms 01 d and d d.

e is a coiled spring surrounding the settingrod between a pin passing through said rod and the lower guide-bracket a, and adapted to return the set-rod upward after it has been pulled down by the handle shown in the drawings. After an arm S has escaped from the corresponding hook T, and the bell has been rung and the proper pointer has been turned to avertical position, it may be brought to its normal horizontal position by pulling down the setting-rod, causing the proper one of the arms d or d to strike and depress the corresponding arm R, and lifting the said arm S again into engagement with the hook T, from which it has escaped. A cross-rod 29 is passed through an opening in the setting-rod near the upper end thereof, limiting the descent of the setting-rod and preventing the straining of the spring.

The numbers 1 2 3 4:, which the openings for the journals of the shafts P bear, also indicate the particular points from which a signal may be sounded. In practice the dialplate would be marked with particular names showing said points or localities more specially. If the bell is sounded simultaneously from two or more points, it is evident from the foregoing description that the pointers for all said points will be turned up.

The parts S D may not be semi-disks, but may be merely arms widened below to lie upon the bellows. The semi-disk shape is, however, preferable.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a base or support provided on its face with bellows connected by tubing with a pneumatic call, of a rockshaft supported from the base in bearings projecting from the face of said base and provided with a radially-projecting arm, a shifting bar having a lateral pin engaging the arm of the rock-shaft and connected at its upper end to the spring-controlled alarm mechanism, an indicator-finger for designating which alarm has been sounded, and a setting-rod for drawing the indicator finger into its initial position after an alarm has been sounded, substantially as specified.

2. The combination, with a base or support having two or more bellows connected with pneumatic tubes, of a rock-shaft having semidisks engaging two or more of said bellows, brackets secured to the casing and provided with projecting arms having parallel bearings for spring-actuated shafts P, journaled in said bearings, provided with curved arms and short straight arms, pivoted bifurcated pieces engaging the short arms of the shafts P and the face of the bellows, a setting-lever having cross-arms, a shifting-rod connected to the gong-striking mechanism, and a retracting-spring for causing the alarm to be sounded on the return movement of the push bar, substantially as described.

3. In a pneumatic indicator, the combination, with the bellows, the mechanism constructed, substantially as described, to inflate the bellows, and the bifurcated pivot at its bend upon a bracket attached to the casing and having one arm bearing on the bellows and the other arm provided with a downwardly-pointed hook at its end, of the short shaft journaled in bearing-brackets of the main frame and provided with an arm to be engaged and held up by said hook, the pointer on the extended front journal of the said shaft, and the spring surrounding the shaft and partly turning the same when said arm and hook are disengaged, substantially as specified.

4. The combination, with the pivoted bifur cated lever having a depending hook on the end of its front arm, the short shaft provided with an outer arm to engage said hook, and an inner arm projecting laterally downward and inward, and the pointer mounted on said shaft, of the settiug-rod moving in guidebrackets secured to the casing and provided with a lateral arm adapted to engage and depress said curved arm and engage the opposite arm with the hook and bring the pointer into its normal position, and the spring returning the setting-rod upward after it has been depressed, substantially as specified.

5. The combination, with the bellows, the mechanism, substantially as described, to inflate the bellows, the rock-shaft provided with a depending arm to rest on the bellows and an axially-extending arm, and the pushrod connected at its upper end to the hell or signal mechanism and having an arm to engage upon the axial arm of the rock-shaft, of the pivoted bifurcated lever with its rear arm resting on the bellows and having a hook on its front arm, the short shaft having an arm to engage said hook, the spring surrounding and turning said shaft when its arm is released, and the pointer on the extended journal of the shaft, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
